alfworld-receptacle-preparer

# Instructions **Trigger:** This skill is invoked when the agent's goal requires placing an object into a target receptacle (e.g., "put X in/on Y"). ## Core Procedure 1. **Navigate:** Use `go to {target_receptacle}` to move to the target receptacle's location. 2. **Observe:** Upon arrival, carefully read the environment's observation. It will describe the receptacle's state and any contents. 3. **Analyze & Prepare:** Based on the observation, determine if the receptacle is ready. * **Ready State:** The receptacle is described as present and accessible (e.g., "On the garbagecan 1, you see a cd 1."). No further action is needed. Proceed to place the object. * **Blocked/Closed State:** If the receptacle is closed, latched, or obstructed, use the appropriate action (`open {recep}`, `toggle {obj} {recep}`) to prepare it. * **Invalid Target:** If the observation indicates the receptacle does not exist or cannot be interacted with ("Nothing happened"), you must abort this skill and re-plan your task strategy. 4. **Confirm:** After any preparatory action, observe the environment's feedback to confirm the receptacle is now ready. ## Key Principles * **Efficiency:** This skill is a preparatory step. Do not spend turns searching for the object to be placed here. That is a separate "search" skill. * **Context:** The observation text is your only source of truth about the receptacle's state. Interpret it literally. * **Idempotency:** If the receptacle is already ready, this skill completes immediately with no action required beyond observation. ## Example from Trajectory **Goal Context:** "find two pen and put them in garbagecan." **Skill Execution:** 1. Thought: "I'll check the garbage can first to ensure it's open and ready to receive items." 2. Action: `go to garbagecan 1` 3. Observation: "On the garbagecan 1, you see a cd 1." 4. Analysis: The garbage can is present and accessible (a CD inside does not block new items). It is **ready**. 5. Outcome: Skill completes. The agent proceeds to `put pen 3 in/on garbagecan 1`.
